Subpart Ja: Inert Coatings Assure Refinery Compliance

May 23 2014 sulfur analysis


Subpart Ja regulations for US refineries will cover almost all refinery flares by November 2015.  Refiners are now upgrading and modifying flare systems to comply with the New Source Performance Standards (NSPS).  The standard will impact several refinery units:

  • Fluid Catalytic Cracking Units – after May 14, 2007
  • Fluid Coking Units – after May 14, 2007
  • Delayed Coking Units – after May 14, 2007
  • Fuel Gas Combustion Devices (except flares) – after May 14, 2007
  • Flares – after June 24, 2008
  • Sulfur Recovery Plants – after May 14, 2007

A recent paper by Spirit Environmental summarizes compliance standards and offers a concise overview of the standard.  You can also read the complete regulation on the EPA website.

SilcoTek® coatings assure Subpart Ja compliance by coating all sampling and transport pathways with inert and high durability coatings. 

SilcoTek coatings improve performance:

  • Eliminate false positive/negative readings due to H2S/sulfur adsorption
  • Assure reliability by reducing moisture contamination
  • Reduce H2S/sulfur corrosion
